Is 64% battery health with only 294 cycles abnormal?

How are you determining battery health? Apple judges a battery to be needing to be replaced when it reaches 1000 cycles OR battery capacity falls below 80%, whichever happens first. In your case, the battery capacity has fallen below 80%, in fact 64% is much lower.

The Macbook Air M2 was sold by Apple July 2022 through March 2025. You indicated that you have been using yours "since June 2024." Did you obtain it new from Apple then? Or was it obtained used? If it was used (pre-owned), then the previous owner might have used it in a way that could accelerate wear/tear. Examples of that could be: letting it sit unused for long periods of time; running it down to zero charge repeatedly; subjecting it to very hot or very cold temperatures.

Have you ever done any of those things yourself?

In any case, the warranty has long expired, if you have AppleCare+ you can get a new battery under that program. I think you should replace the battery one way or another because a degraded lithium battery can start to swell or leak and damage other components. And 64% means it won't last very long on a charge anyway.

Yes that is abnormal. Damage to your battery will occur if you continually let the battery drain to nothing. That is true for any Lithium-ion battery. The Mac will try and protect the battery by turning off before that occurs and giving you warnings when the battery is running low, but action needs to be taken to charge the battery for long term care.

Yes.
